Our WiFI is not working once again.....

Our wifi is once again not working, this happened prior to the storm last week. Despite getting a reference number online from Telkom, we have had no communication from them whatsoever. Our reference is 473CRK131115.<br> <br> Telkom is selling some nice products, however, it all falls short when their after sales care remains very slow and is sub standard. I have previously experienced technicians claiming to have attended to the problem when nothing has been done.(The last long winded fault before the current one) I am not impressed.
